Terabyte data sotrage for archival applications
Recently, the amount of digital data have been increasing rapidly by highly developing digital information devices and network. For archival data storage, more high data capacity and fast data transfer rate are required as well as the life time of the storage media. Optical disk memory attracted much attention because of strongness for disaster such as flood and low total cost for long time storage such as 20 to 30 years. We have been developing a reflection-type holographic data storage by using three-dimensional speckle shift multiplexing. This proposed system has a potential to increase the storage capcity with more than 1 terabyte in a 12 cm disk with 0.5 mm thickness. We have developed a simulator to evaluate the holographic data storage and have many strategy to increase the capacity.
